DA0-002 Data Governance Practice Question
A regional bank's analytics team maintains a data catalog. A new analyst needs to know which column in the 'loan_applications' table stores the customer's country of residence, what values are permitted, and who owns the table. Which data governance artifact should the analyst consult FIRST to obtain all three pieces of information?
⚠ Common exam trap
The trap here is assuming a business glossary contains column-level value constraints and table ownership, when it only defines business terminology.

Correct answer & explanation
✓
The data catalog, because it combines technical metadata, business definitions, permitted values, and ownership in one searchable inventory
A data catalog aggregates metadata from multiple governance artifacts into a single searchable inventory, so it can answer definitional, value-domain, and ownership questions in one place. A data dictionary alone lacks ownership, a business glossary lacks column-level value constraints, and lineage addresses flow rather than meaning. The catalog is the artifact designed to unify these perspectives.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
The enterprise data dictionary, because it defines each field's business meaning and permissible values
Why it's wrong here
A data dictionary documents field-level metadata such as definitions and formats, but it typically does not identify the accountable data owner or the stewardship contacts for the table. The analyst would still need to consult a separate ownership record, so this artifact alone does not satisfy all three requirements in the scenario.
- ✗
The data lineage diagram, because it traces the column's origin and downstream transformations
Why it's wrong here
Lineage shows how data flows from source systems through transformations to reports. It answers provenance and impact questions, not the business definition of a column's values or who is accountable for the table. It is valuable for troubleshooting pipelines but does not provide the permitted values or ownership the analyst needs.
- ✗
The business glossary, because it lists approved acronyms and metric formulas used across the bank
Why it's wrong here
A business glossary defines business terms and standardized metrics, which helps with consistent reporting language. However, it does not map those terms to specific physical columns or enumerate allowed values at the field level, and it generally lacks table-level ownership details, so it cannot fully answer this request on its own.
- ✓
The data catalog, because it combines technical metadata, business definitions, permitted values, and ownership in one searchable inventory
Why this is correct
A data catalog is the central inventory that consolidates technical metadata, business definitions, value constraints, and stewardship or ownership assignments for each asset. Searching the 'loan_applications' entry surfaces the column meaning, allowed values, and the accountable owner together, which is exactly the consolidated view this new analyst requires.
